Determine whether the given axis-aligned box is partly or completely within or outside of the frustum defined by <code>this</code> frustum culler
and, if the box is not inside this frustum, return the index of the plane that culled it.
The box is specified via its min and max corner coordinates.
<p>
This method differs from {@link #intersectAab(double, double, double, double, double, double)} in that
it allows to mask-off planes that should not be calculated. For example, in order to only test a box against the
left frustum plane, use a mask of {@link #PLANE_MASK_NX}. Or in order to test all planes <i>except</i> the left plane, use
a mask of <code>(~0 ^ PLANE_MASK_NX)</code>.
<p>
In addition, the <code>startPlane</code> denotes the first frustum plane to test the box against. To use this effectively means to store the
plane that previously culled an axis-aligned box (as returned by <code>intersectAab()</code>) and in the next frame use the return value
as the argument to the <code>startPlane</code> parameter of this method. The assumption is that the plane that culled the object previously will also
cull it now (temporal coherency) and the culling computation is likely reduced in that case.
<p>
The algorithm implemented by this method is conservative. This means that in certain circumstances a <i>false positive</i>
can occur, when the method returns {@link #INTERSECT} for boxes that do not intersect the frustum.
